I had some issue in compiling DifferentialEquations after an update so I removed it re-add it. Here is the output. Please see the last couple of lines.

This happens due to compatibility constraints.

Agree. So what is the way out?  
The packages which were functional earlier have started throwing errors after the update.

Try now. A big update was in the middle of occurring, and now a new DifferentialEquations.jl was just released which is compatible with the very latest of the solvers.

Thanks I did an update today as suggested by you. Then I tried to precompile DiffEq and got a warning. Susequently I also tried to run some code (which worked fine two days ago), but it threw an error on using Ensemble.

```julia
To resolve the warning I updated the Julia Manifiest.toml file and Project.toml file of DiffEqFinancial for the missing dependency of Markdown and LinearLAlgebra and recompiled DiffEq. It completed succesully. The Ensemble error still remains. Not a big issue for me but thought about updating you.

I found the issue with plotting DiffEq ensemble . Reverted StatsPlots pacakge to v0.19.0 from v0.20.0 and it works.

Ooh, umm… StatsPlots’s latest release is v0.12.0

[https://github.com/JuliaPlots/StatsPlots.jl/releases](https://github.com/JuliaPlots/StatsPlots.jl/releases)

so that’s interesting 🙂.

BTW, the DiffEqFinancial warnings should be gone now.

True. My mistake. Reverted from 0.12.0 to 0.11.0. Got confused with IJulia version.  
After updating Manifest.toml for the missing dependency of “DiffEqFinancial”, the warning is gone.

Not sure what’s going in here, will dig into it. It looks like @Ajaychat3 is talking about Plots, but its latest release is at least 0.25.

Sorry, didn’t see your reply to Chris.

I’ve tried your example code, and it has the same error on my machine.

```julia
using DifferentialEquations, Plots
α=0.08;β=0.3;u₀=1.0
f(u,p,t) = α*u
g(u,p,t) = β*u #*sqrt(dt)
dt = 1//250 # 1/16 in fractional form
tspan = (0.0, 10.0)
prob = SDEProblem(f,g,u₀,tspan)
ensembleprob = EnsembleProblem(prob)
sol = solve(ensembleprob,SRIW1(),EnsembleThreads(),trajectories=100)
summ = EnsembleSummary(sol,0:0.01:10)
plot(summ,labels="Middle 95%")

```

Seems to be a problem which occurs when plotting the ribbon.

Relevant versions:

It seems that the ribbons are converted here:  
[https://github.com/JuliaPlots/Plots.jl/blob/236aaed2a30c165e704e2233d08341f2595fc6e1/src/series.jl#L139](https://github.com/JuliaPlots/Plots.jl/blob/236aaed2a30c165e704e2233d08341f2595fc6e1/src/series.jl#L139)  
and plotted here:  
[https://github.com/JuliaPlots/Plots.jl/blob/236aaed2a30c165e704e2233d08341f2595fc6e1/src/series.jl#L159-L160](https://github.com/JuliaPlots/Plots.jl/blob/236aaed2a30c165e704e2233d08341f2595fc6e1/src/series.jl#L159-L160)

Still not sure why that would happen…for what it’s worth, going to Plots v0.26.0 (by `]pin Plots@0.26.2`) seems to resolve the issue.

Edit: I’ve opened a PR to fix it here: [https://github.com/JuliaPlots/Plots.jl/pull/2186](https://github.com/JuliaPlots/Plots.jl/pull/2186)

Waiting to merge it till I can figure out how to add some tests.
